[HD2 Android Q&A, Help & Troubleshooting and Genera] Cyc.:
Had my HD2 for over a year now and finally got fed up of lack of WinMo apps, which my housemate with his iPhone loved to point out all the time. So I decided to try out Android a few days ago.

Read all tutorials etc and installed Skink's clean desire rom v1.3 using cwm. Got everything set up and was really pleased with my shiny new phone. Everything was working like a dream!

I decided to get a new 16 GB SD card as my 8GB card was full of music etc. Here is where the problems started...

To get all data onto 16GB SD card:

I partitioned it using cwm using same size partition size as on 8GB (1024mb)

Copied all files on 8GB fat32 partition onto 16GB fat32

With the 8GB SD card in the phone did a backup using cwm

Copied backup onto 16GB card inserted it into phone and did a restore

Now the fat32 and ext3 partitions on the 16GB card and 8GB card should be the same, so everything should carry on working fine when i boot up my phone.

It didn't :( I just kept getting lots of stopped unexpectedly errors until finally everything stopped loading even the home screen, and I'd have to remove battery. However if I just put my old 8GB card in everything worked fine as before :confused:

So after much frustation I gave up on this method and decided to just wipe everything on 16GB card and start from scratch:

Formatted 16GB card

Repartitioned it using cwm

wiped data, cache, dalvik cache

installed clean desire rom from sd card

booted up started reinstalling all apps etc

Now here is where things get very strange, I'd start reinstalling apps and reconfiguring to how it was before and then randomly I'll get a stopped unexpectedly error, like process.android.media or something similar. But it seems as if everything would carry on working, then slowly I get more errors until for example as soon as you click on internet you get an error and it closes.

I believe the problem lies with the sd card seeing as that is the only thing that has changed. I also think this rom stores more than just apps on the sd card. Because after I get a few of these stopped unexpectedly errors nothing is saved on the phone. For example I'll change the ringtone from x to y click ok, but when I click back on change ringtone it's still on x. But I can still play music that is stored on the sd card. After I reboot the phone for a while I can make changes and they are persistent but eventually I end up back at this strange state. It's almost as if I can read from the SD card but not write to it.

Another example when I've got to this strange state, I'll add a folder to home screen, add apps into etc. But when I restart the folder has gone.

If I reinsert my 8GB card and do a restore, I get everything back and it works perfectly. But I want to use my 16GB card, that's why I bought it!

My questions are:

Does anybody have an idea of what is going on when it gets into this strange state?

Does anybody know how to fix it?

Is there some way of testing the SD card?

Should my first method of getting all data onto new sd card have worked?

SD Cards are:

Samsung 8GB class 6

Transcend 16GB class 6

Sorry for the long post, any suggestions are greatly appreciated :)
